BioCycle Treatment System

The BioCycle is a residential sized wastewater treatment plant that is designed to treat household wastewater before it is discharged to the drainfield. The BioCycle, like the other AWWTS systems, provides an aerobic environment in which microorganisms flourish by consuming the organic wastes. By reducing the strength of the organic waste, the wastewater coming out of the BioCycle is cleaner than what would come out of a conventional septic tank. As a result, the MOA, Development Services Department allows a reduction in the size of the drainfield versus what would be required for a conventional septic system. The benefits are as follows:

  • Drainfield sizes are reduced by as much as 75%. The BioCycle installation will reduce the aesthetic impact (less lawn and trees destroyed), enhancing the value of the property.
  • Small lots which could only support a 2 or 3 bedroom conventional septic system can often install a BioCycle in the same area that will allow for up to a 5 bedroom house. Again, enhancing the value of the property.
  • The life of a drainfield served by BioCycle system should be more than that of a conventional septic system.
  • On undeveloped lots which are very small, the BioCycle system makes it easier to find room for the primary and reserve drainfields. Because of the reduction in drainfield size, only two small drainfield sites would be required. In short, a lot that may have not been developable with a conventional septic may now be a developable piece of property.


In theory, if properly maintained and operated, the BioCycle system is capable of producing an effluent that will not biomat, and fail the drainfield.


Costs for a BioCycle installation, including test holes, engineering, permits, and contractor fees, typically averages $25,000 - $35,000. As is the case with the other Advanced Wastewater Treatment Systems (AWWTS), the price is not cheap; however, the benefits may out weight the costs.
